Iran “dismissed the agency’s concerns,” the International Atomic Energy Agency said today in an 11-page restricted document obtained by Bloomberg News. “ Iran considered them to be based on unfounded allegations.”

The report, distributed to IAEA member states, was published three days after inspectors’ talks with Iran broke down. Inspectors said Iran raised the number of machines used to install uranium at its Natanz complex by 14 percent and began enriching material at its Fordo mountainside complex.

The IAEA, while verifying that Iran hasn’t diverted declared uranium stocks, reiterated that the government still hasn’t proven the peaceful intent of its atomic program. The U.S. and European allies accuse Iran of seeking nuclear weapons while the Persian Gulf nation’s leaders say they seek only energy and industrial applications from nuclear technology.

Iran increased its supply of 20 percent-enriched uranium to 109 kilograms from 73.7 kilograms reported in November, the IAEA said. Iran has produced 5,451 kilograms of uranium enriched to less than 5 percent compared with 4,922 kilograms in the last IAEA report.
